Carbon Preference Index(CPI). Generally the ratio of abundance of odd over even carbon number paraffins, specifically calculated over the C24-C34 range. Hydrocarbons derived predominantly from terrestrial sources and/or at low maturity exhibit a predominance of odd-numbered alkanes(resulting in a high CPI) ;this feature disappears with increasing maturation level(CPI approaches 1. 0). 5, record 2, English, - carbon%20preference%20index

... case studies show that in ancient detrital sediment the predominance of the original odd n-alkanes of high molecular weight is preserved mainly in relatively shallow shales and silts, where degradation of kerogen has not yet started ... With increasing maturity, and odd-even preference (also known as CPI: carbon preference index) of about 5:1 in shallow detrital material is reduced to around unity in the zone of oil formation, as a result of thermal degradation and the introduction of new alkanes, which dilutes the original odd-even predominance. 3, record 2, English, - carbon%20preference%20index
